 GUIDs need to be set before attaching a VF to a VM. It should be possible to change state (simulating unplugging the cable) while a VM is using a VF but I haven't tested this.
+  # ip link set dev ib0 vf 0 node_guid 58:49:56:0e:59:15:03:02
+  # ip link set dev ib0 vf 0 port_guid 58:49:56:0e:59:15:03:02
+  # ip link set dev ib0 vf 0 state enable
 I keep the whole configuration in /etc/rc.local.
